Energy Gaps in a Spacetime Crystal
arXiv:0910.2646 · doi:10.1016/j.physleta.2009.10.034
Abstract
This paper presents an analysis of the band structure of a spacetime potential lattice created by a standing electromagnetic wave. We show that there are energy band gaps. We estimate the effect, and propose a measurement that could confirm the existence of such phenomena.
